BAG-CLEANER.

fl 10 vall Iiti/wm t may conce/Wi Be it known that'l, .TosiiPi-I C. CHAMP,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and `State of Pennsylvania', have invented certain new and useful lmprovements in fBag-'Cleaners of which they following is a specification.

Mypresent inventionl relates to improve- Vments in devices which have for their especial obJect a full and complete emptying, or

discharge of material of a pulverulent or.

pulverized nature, from the bags wherein such material is packed, and to the accomplisliiiientof the purpose named, the said invention contemplates the provision `of simple, durable andv easily operated means,

whereby a. bag, after the material packed whereby such of the material as has found lodginent upon the surface, or in the body of said bag, may be dislodged or shaken therefrom and caused to fall into receptacles placed to receive the same, and to the endl noted the invention 'consists in peculiar means and mechanism whereby a bag, when emptied of material and mounted upon a movable support within a suitable inclosinge casing, is subjected to a sudden and sharp movement in opposite directions substantially in the manner hereinafter described,l and illustrated in the accompanying draw-y ings whereby such material as has found lodgment upon said bag, is dislodged therefrom.

Of the rdrawings referred to: rFigure l, illustrates in side elevation, thedevice as it appears when ready to be actuated for thev purpose named. Fig. 2, is a vertical longitudinal section, taken through the actuating shaft, its inclosing casing and the parts thereto connected,l to clearly illustrate the Lconstruction of the same.

Fig. 3, is a transverse sectional view taken on the line fr, of Fig. l, looking downward toward the basev of the device. Fig. 4, is a similar transverse sectional view taken on the line y, jy. of F ig. l, and lookingrdownward to- Fig. 5,r is an enlarged sectional det-ail view taken on the line e, e, of Fig. l, through the tubular casing ofthe actuating Shaft and the shaft actuating device. to show the connection of Specification of Letters Patent. y Paten-[ged Degfj, 1915 i Application led February 21, 1914. Serial N c. 820,235.

a portion of the actuating shaft, its tubular casing and thev device lby which said shaft is actuated. Figs. and S, illustrate modifications ofthe ineansfor returning the actuating lever, or treadleito starting` position. Fig. 9, illustrates, in elevation, a portion of the lower end of the'actuating shaft, showing thereon modified means forrotating said shaft. FigxlO, shows in plan view, the de'- vic'e which co-acts with Vthe, shaft shownin Fig. 9, to rotate the saine. i

It is a rfact wellknown to those vwhose business or occupation necessitates the lliandling, or einploynientand use of pulverized material, rsuch for instance, as hydraulicv lime, or cement, that avery considerable loss occurs from and is `consequent upon the lodginent of the dust like particles, of which such pulverized material consists, upon the surface or in the body itselfof'the container in Awhich such material is packed.l The fact above setforth, is particularly true when the bag wherein the material is packed, is made of burlap, .or of material analogous thereto, because of the fact that'thesurface of such material is rough andcoai'se, and therefore peculiarly adapted to receive and to retain sudden jars, or shakings in opposite directions through the medium of simple and easily actuated devices, thus saving for use, material that otherwise would be lost.

' Referring to the drawings which form a part of this specification, wherein one adaptation ofiny invention is shown and in the several'views of which similar letters and numerals of reference denote like parts, `l,

designates a base `plate which, although here y shown as being of metal and'fin circular shape, may yet be made of any desired mai terial, suitable for such purpose, and of any desired form and shape, and I provide said base plate at, or near its middle, with an` aperture 2, screw threaded to receive thek lower screw threaded end of a tube, which V .extends thence, linjupward direction, l to thef desireddistance to support a shaft 4, whichcentrally disposed and extending within .the

tube 3, is provided `at Vits'l'ower end with a" pivot .5, that is jou'rnaled in a bearing block 6, secured within 'the lower vend of the tube '3, as shown. Y. 1 1 The opposite upper end of the shaft 4,

extends through and lightly contactswith a centrally apertured bearing block 7, Which, secured kto theuppei'a'Y end of the tube 3', forms journal bearing for the shaft has shown.

in Fig. 2.

l providethe upper, 4end of the shaftk l,

above the tube 3, withacirciilar plate, or wheel 8", whichrigidlysecur'ed'to said shaft rotates therewith, as willbe presently/'described, for a purpose,l to be. hereinafter set i forth.' l also provide the shaft 4, ata .pre-

- /wi'tha bearing bloclr 9, through which said` determined' distance above thebaseplate l,

sha ft extends, and with which 'it lightly contacts for the purpose. of preventing lateral deflection lof said shaftwhen it is'operated,` as willl be presently described. i

I provide that the shaft et, shall, when in' actioinbe rapidly rotated yin opposite` directions, to impart a shaking, or slattmg move- `ment tothe bag which is to becarried upon said'shaft, as will presently be more fullyl explained, and to such end l provide the lowerjend ofthe shaft fl, with a groove -1.0, andjextend said groove about the shaft in spiral direction to engage ka pin'11, that' proje'cts'into said groovefrom a short ,blockv or nut 12, which apertured for the passagel therethrough of said shaft 4, is adapted to slidek freely up and down Within the .tubular casing 3, upon the shaft l, therein contained.

I'provide that the block ornut 12, shall be held from rotation within the casing', to which end lk provide the tubular casing-3, upon v'its opposite sides and near its lower end with slots 13, through which the screw threaded shanlrs of bolts 14'extend to andv into the opposite sides or nut 12, see Fig. 5; l

I arrange that the sliding block or nut12,

of the sliding block vshall be movedup andA 'down within the tubularcasing 3, to rotate the shaft 4, and to such end provide that the bolts lll, upon the opposite sides of thecasing 3,shall respectively, extend through. short slots 15, one

.of which is formed through each of the rear- "wardly extending arms 16, and 17, of a treadle 18, which,fhinged at V19, to astand- `ard 20, that projects upwardly from the,v vbase plate l, is adapted to be moved in downward direction,by pressure, and to be' 'f returned' to its normal. elevated position by a spiral spring 21, which surrounds the lower portion. of' the shaft 4:, and bearsat its opposite ends respectively upon the base 1,"and the lower side of thev block or nut v12,

' .By the foregoing described construction of the Yoperativeparts comprisedm mym-V `vent/ion, it willebe readily understood v that a bag, of textile fabric, will-#when placed j'in position upon the circularplate,or-wheel 8, as indicated in Fig. 2, bythe numeralf'22,

and ysubjected to. thebaclr andforthshaking, f

l,or slatting due to the action of the shaft Zt,-

be thoroughlyl cleansed from such particles of pulverized material 'as mayV have .re-

mained u on its surfaceV or in its'texture Y after 'uch bag had been'fdiscliarged in Lthe ordinary manner. For the purposejof Vsaving the material so discharged from the bag, l provide that the 4operation of cleansing the same', as above noted, shall be carried forward within a'suitablein'closing casing,

and that the materialY discharged from the'l bag, shall be caught. in suitable receptacles.

provided for such. purpose'.

To the'ends lastabove named, l provide the device, at a suitable distanceabove the hase plate 1, thereof, kwit-han open" ended cylindricalv casing A23, which, arranged concentric with `the tubular` casing 3, of the shaft e, issecuredto the r upper ends of supports 2l, which extend'from and are rigidly secured, at tlieirlowerends to the base l, see Figs. 1 andl 3', to maintain the casing 23,' iii proper lposition noted.

l lalso arrange, immediately below and partially surrounding vthe .casing 23'a receptacle 25, for the materialthat is fdis charged from the bag, so arranging said re? ceptacle as regards the casing 23, that its, circular inclosing wall 26, shall be concen-y ioo tric with said casing 23, while its bottom'v27,VV

preferably cone shaped shall projectf up- 'wardly within the lower end of the casingV 1'05' 23,v at .a short distance therefrom, so that material falling upon said cone shapedbottom 27, froml .the bag, when the device `is operated, shall pass upon such bottom 27, below the lowerz-edge of the casing 23, to'

the receptacle 25, to 'be dischargedV there-v from through a spout 2S, 'which extends' from one side of said receptacle as shown.

The receptacle v25', is held in proper posi-l ht against the tubular casingl 3,4of theV shaft Ll.

l provide that the operation of cleansing thebags shall be confined within inclosing walls, to which end, larrange' afcylindrical casing 29, having its upper end closed and its lower end open, vabove and concentric with the casing 23,v and in 'position to be drawn'downward, oveijfgthe bag when it is 1n position upon, the circular'support, or wheel 8, and into the saidrcasing 23, until f casing 23.

' ing' similar to that 1,163,1jei

its lower end shall rest upontlie bottoinQT, of the receptacle 25, as shown in Fig'. 2, at which time the operation of cleansing the bag is to beVv performed, and after which said casing 29, is to be raised, to permit the removal of the cleansed bagfrom the support 8, and the placing of'anoth'er thereon, as fwell as to permit lthe material, shaken from said bag to slide down the cone shaped bottom of the receptacle 25, to the wall 26,k thereof to be withdrawn therefrom.

It is to be noted that the exterior surface of the bag ,inclosing casing 29, is purposely proportioned to lightly Contact with the internal surface of the casing 23, so vthat when the device is in operation, the bag,- inclosing hearing 3l, instead of having a journal bear-l shown at 5, in Fig. 2, see

i Fig. 6.

lf rdesired the treadle 1S, may, when pressed downward by the foot of an operr a tor, be returned to normal starting position by a counterweight 3Q, that is ar ringed upon an extension ofr said treadle, beyond its fiilcruin, as shown in Fig. 7, instead Lof being returned to normal starting yposition by a spiral Aspring- 21, held within the; casing' 3,.as shown in Figs. l and 2, or such treadle 1S, may. at its rrear end below its pivotal point 19, be provided with a dependingarm 83, to receive at its lower end, one end of a coiled spring 34, the opposite end of which, is connected to a support 35, as shown `in F in'. S, instead of the construction shown in Figs. 1 and 2.

In Fie'. 9, I show a device which may be employed instead of the tool cut spiral `groove l0, in the shaft 4, such device consisting of a flat piece of metal of proper size, so twisted upon itself that its side edges shall extend in spiral direction, as shown at 36, and 4provided at its lower end with a journal 87q to engage a bearing in the lower end of the tubular casing 3, and at its up-y per end, with a step 38, to enter a recess 39, in the lower end of the shaft 4t, and having an actuating; nut 40, peculiar to the twisted portion 36 of said shaft, inthat 'said nut is formed by placing a section of tubing, of proper length about the twisted section 36,

and pouring` heated Babbitt metal, or other suitable material, into the tube section.

about such section 36, to foi'm the actuating nut 4.0, shown in Fig. 10.

rrlheoperation of the device will, it is thought, be understood from the .foregoing description, Vtaken in connection with the accompanying drawines,it only beingnecessary to here state, that the bag to be acted upon, is placed in position upon the rotatable disk, or wheel 8, as shown Fig. 2, the inclosing casing 29, drawn down to cover 'said bag, as shown in Fig. l, andthe trcadle 18, forced up and down any desired number of times, to accomplish the desired end.

- vllWhile I'have herein shownf'and described f one rzulaptation of myinvention, Iyet do not wish to confiney myself solely to such adaptation, Vas different yadaptations of suoli inventionmaybe made toaccomplish the saine result, I therefore lclaim the right to' make'any and all such modifications of said invention, as shall fall withinthe scope and limit of the claims hereto appended.
